Definitions
- This invention relates to a repositioning apparatus and in particular to an apparatus arranged to reposition substantially forward and rear facing flaps on a carton automatically.
- corner gussets may be provided extending between the carton side walls and the bottom and/or top carton walls, as can be seen in EP-A-0 459 658.
- retention panels may be provided to extend across the upper end and/or lower end of the carton, as can be seen in EP-A-0560 658.
- wraparound cartons may be provided with end doors which are folded to a closed position. As can be seen in EP-A-0 499 426, when such cartons are for use with bottles having tapered necks, the doors may be provided with upper portions that are angled against the necks of the outermost bottles.
- the wraparound cartons are typically applied to the container group by automated packaging machinery, in which the container group moves along a conveyor.
- the carton blank is applied to the top or bottom of the group, with the side walls extending transversely of the conveyor direction.
- the carton is then wrapped around the group.
- the retention structure is typically folded into position either during or subsequent to the wrapping operation.
- upper portions of the end walls may also be angled against the necks of the outermost bottles.
- Such cartons are also loaded on automated packaging machinery, in which the container group moves along one or more conveyors. If the sleeve is applied vertically to the group, such as by lowering from above, the angled upper portions may be folded into position after the carton has been applied to the group.
- the positioning of the flaps comprising the retention structure is made difficult because the flaps are located at both the forward and trailing ends of the carton as it is moved along the conveyor. Thus, both forward and rearward folding of the flaps are required.
- packaging machines operate at extremely high speeds, with container packaging machines commonly packaging 250 containers per minute, there is a requirement for a means of positioning these flaps which can be automated without either damaging the containers or cartons, or slowing down the packaging machine.
- An object of the present invention is to provide a method of and apparatus for automatically repositioning flaps on a carton at processing speeds comparable with that of container loading machines.
- a further object of the present invention is to provide an apparatus for loading containers into cartons, which includes an apparatus for repositioning flaps on the cartons in order to secure the containers in place in the carton.

- FIGURE 4 is an illustration of a carton with which the present invention may be utilised
- FIGURE 5 is a plan view of the operation of a dual apparatus at specific intervals throughout the repositioning process
- FIGURE 6 is an electrical block diagram of the apparatus of Figure 1 ;
- FIGURE 7 is a schematic block diagram of a container loading apparatus inco ⁇ orating the apparatus of Figure 1.
- Figures 1 and 2 illustrate an apparatus 10 arranged to reposition substantially front and rear facing flaps 12 and 14 on a carrier 16 being transported along a feed path 18 of a standard apparatus for loading bottles into a carton.
- the apparatus 10 comprises a continuous belt 20 having, in this embodiment, three lugs 22 attached thereto.
- the belt is placed around a drive roller 24 and a follower roller 26.
- Controlled movement of the drive roller 24 powered by a drive motor 28 ( Figure 6) under the control of a control means 30 ( Figure 6) causes the drive roller 24 to rotate causing the continuous belt 20 to move which in turn causes the follower roller 26 to rotate.
- the drive motor 28, is a servo motor.
- the continuous belt 20 may be manufactured from a frictional material such as rubber and may be caused to move due to friction between the roller 24 and the continuous belt 20.
- the drive motor may have a toothed section as illustrated in Figure 3 each of the teeth being received in co-operating recesses 27 in the continuous belt 20, during use, in order to move the belt 20.
- rollers 24 and 26 are positioned adjacent a feed path 18 in a bottle loading apparatus such that movement of the belt 20 will periodically bring lugs 22 into the feed path 18.
- the apparatus 10 is operable such that the individual lugs 22 are periodically positioned in the feed path 18 in front of cartons 16 causing each carton 16 to contact the lug 22 and in so doing to reposition the front facing flap 12 on the carton 16.
- the continuous belt 20 is positioned at a height such that the lugs 22, when in use, will contact the front and rear flaps 12 and 14 of the cartons 16 so as to move the flaps. This is explained further with reference to Figures 4 and 5.
- the apparatus 10 is further operable to increase the velocity of the lugs periodically so as to bring the individual lugs 22 into contact with the rear facing flaps 14 of the cartons 16, thus repositioning the rear facing flap 14.
- a single variable speed continuous belt 20 is utilised.
- a plurality of belts may be utilised.
- a single roller with one or more lugs 22 attached thereto may be utilised without the use of a continuous belt.
- the lugs are preferably in the form of a T- shaped member, positioned at equal intervals around the continuous belt 20.
- the base 32 of each lug 22 is connected to the continuous belt 20 such that the first arm 34 of the T will project forward of the base 32 and the second arm 36 of the T will project rear of the base 32 with respect to the feed path 18, when in use.
- the end portion of the front and rear facing arms of the T are provided with resilient portions 38 and 40, formed for example from rubber, so as to minimise the likelihood of damage to the bottles within the cartons 16 during use.
- the apparatus 10, as illustrated in Figure 6 includes a control means 30 arranged to control the speed of the continuous belt 20 during use.
- This control means may be a dedicated processor or may be a control means for a packaging machine with which the apparatus 10 is used, which is adapted to control the apparatus 10.
- the control means may preferably be a known, programmable servo control system.
- the control means 30 receives information from a sensor 42 arranged to detect the speed of the continuous belt 20; which may detect the speed of the belt directly or may detect the speed of the drive roller 24.
- the apparatus 10 includes means in the form of a sensor 44 for receiving information regarding the speed of the cartons on the feed path 18 which is transmitted to the control means 38.
- the apparatus 10 is mounted on a pair of rails 48 which run perpendicular to the feed path 18 thus enabling the apparatus 10 to be rolled into an operating position wherein the or a lug 22 projects into the feed path 18, when in use, and rolled out of this position to a rest position in which the or a lug 22 does not extend into the feed path 18.
- the apparatus 10 can be withdrawn when the packaging machine with which it is used is loading cartons which do not require the repositioning of flaps.
- Figure 4 illustrates such a carton 16 having a front wall 50 and a rear wall 52 each of which are divided into a lower portion 54 and an upper flap 12 and 14.
- the flaps 12 and 14 and the lower portions 54 of the front and rear walls 50 and 52 are each separated by a crease (or fold) 56 which allows the flaps to pivot with respect to the lower portion 54 of each wall.
- a second crease (or fold) 58 is located on each of the side faces 60 of the carton between the point where the crease 56 joins the side wall of the carton and the top surface 62 of the carton. This crease is provided so that the side wall can bow out slightly allowing the flaps 12 and 14 to reposition against the neck 62 of the bottle 64 within the carton 16, as illustrated by the dashed lines 63 and 65.
- each of the lugs 22 will be arranged not to contact the flap centrally, but instead to contact the flaps at a predetermined position closer to the sides 60 of the cartons 16.
- the apparatus 10 When in use, the apparatus 10 is rolled into a position wherein the lugs 22 will project into the feed path 18 as illustrated in Figure 1.
- the continuous state speed of the conveyor means which transports the cartons 16 is input into the control means 30 using the manual input means 46 ( Figure 6).
- a lug 22 will be arranged to contact the appropriate flap 12 or 14 of the carton 16 at a specific percentage above or below the speed of the feed path, as will be discussed in detail below.
- both the conveyor means used to propel the cartons 16 along the feed path 18 and the continuous belt 20 will increase gradually in speed to a standard running speed. Both of these apparatuses will be controlled such that this process will be gradual and no damage will occur to the cartons 16 or their contents.
- FIG. 5 illustrates one embodiment of the apparatus and five steps of repositioning the front and rear facing flaps on cartons being transported on a feed path.
- step 1 the lugs move into the feed path.
- step 2 the lugs are accelerated relative to the feed path velocity to be brought into contact with and to reposition the rear facing flaps, shown as step 2.
- step 3 the lugs are decelerated relative to the feed path velocity, so that the lugs are brought into contact with the front facing flaps of the next succeeding carton and the flaps are repositioned, shown in step 3.
- steps 4 and 5 the lugs are accelerated to be moved out of the feed path. Rear lugs are then moved into the feed path behind the carton and the above procedure is repeated.
- the speed of the continuous belt 20 is within 1 to 30% less than that of the cartons 16 progressing along the feed path 18.
- the speed of the continuous belt 20 is between 1 and 30% greater than that of the cartons 16 in the feed path 18.
- the continuous belt is moved at a speed 20% less than the speed of the cartons 16 in the first instance and at a speed 20% greater than the speed of the cartons 16 in the feed path in the second instance, as this provides a sufficient force to reposition each of the flaps without damaging the carton 16.
- the speed of the continuous belt 20 is also varied so that the speed of the continuous belt 20 is maintained within these percentage variations.
- a faster or slower speed is required, for instance if a particularly thick caliper of board is used to produce the carton then a greater variation may be required to cause sufficient force to reposition the flaps thereon.
- the speed may be varied if one or two apparatuses are used.
- FIG. 7 is a schematic representation of an apparatus 70 for loading bottles into cartons 16, which illustrates the position in the apparatus 70 of the apparatus 10 for repositioning flaps, in accordance with the present invention.
- the apparatus 70 includes a carton hopper and feeder mechanism (block 72) from where cartons 16 are taken and fed to a mechanism (block 74) which combines bottles and cartons either by wrapping cartons around the bottles or placing bottles in the cartons depending on the type of carton used. Bottles are fed into this mechanism at a predetermined rate and in a predetermined arrangement, from a storage area (block 76). Once the cartons and bottles are united the carton is locked in place by suitable locking means, usually in the base of the carton, (block 78) in a known manner.
- suitable locking means usually in the base of the carton, (block 78) in a known manner.
- the invention is not limited to cartons of this type. As will be recognised by those skilled in the art, the invention, may be used with wraparound or end loaded cartons, and may be used to reposition various carton flaps used for retention and other purposes.
